To calculate temperature, why we multiply 25 with mV?

Answer Posted / carl_ellis

Apparently, your temperature signal is linear across a mV
range, coming from some type of temperature transmitter,
and the mV value represents temperature/25.

If your source is a raw thermocouple signal, then
multiplying by 25 does NOT result in a true temperature
value because
- cold junction compensation has not be applied
- thermocouples are not linear

Temperature transmitters perform both of those tasks, cold
junction compensation and linearization of the output
signal.
